I'm having a problem with my cable TV displaying correctly. I have my HD cable box hooked into the onkyo amp, along with the DVD player, both in Component/HD in, and then out to the TV's HD input. The DVD player works fine in progressive and normal modes.

The cable box works fine on all digital channels, but not on analog channels (2-75 on mine). I get sound on them, but the picture is garbled/wavy.

If I bypass the receiver, and go straight from the cable box to the TV's HD input, same problem, so that rules out the receiver, I guess.

If I use a different video input for TV, say s-video, all channels work fine. Tried a different cable box, same thing.

Didn't you also have problems with your Xbox through a certain set of inputs on the TV? From what I remember of that thread and this problem it sounds as if that set of inputs is set to receive a signal in 1080i or 480p and it just isn't recognizing a 480i signal by itself. Is there a way to choose the display in a menu on the TV itself. Does it have more than one set of component inputs or is it just the one and Svideo and composite on the others? It really sounds like anytime you try to feed a 480i signal into those inputs your getting messed up video, I'd look around and see if there is a FAQ or forum on that TV somewhere, either at the manufacturers site or over at AVS. Or just try to call them to find out what is going on, it really doesn't sound like it is your cable companies fault or their equipments fault.
